Whether you’re working on structural builds or decorative finishes, our timber solutions provide strength, versatility, and sustainability. As a renewable and recyclable material, timber is an environmentally responsible choice for any project.

Treated and sawn, our roof battens support tiles or slates and maintain structural integrity and proper alignment across roofing systems.

Our wide range of timber mouldings includes skirting boards, dado rails, floorboards, architrave, door linings, and lasings. For framing and internal panels, Scant and CLS timber are excellent choices thanks to their smooth finish and dimensional accuracy.

PSE Timber

Planed Square Edge (PSE) timber offers a smooth, finished surface, making it perfect for joinery, furniture making, and interior framing where a clean, professional appearance is essential.
